We are going to take a look at what happens when routing occurs on a network. When I was new to the networking area, I thought that all you needed was the IP Address of the machine you wanted to contact but so little did I know. You actually need a bit more information than just the IP Address !

Enhanced Interior Gateway Routing Protocol

Enhanced Interior Gateway Routing Protocol (EIGRP) is another Cisco proprietary, hybrid (has feature of Distance Vector and Link State protocols), interior gateway protocol (IGP) used by routers to exchange routing information. EIGRP uses a composite metric composed of Bandwidth, Delay, Reliability, and Loading to determine the best path between two locations.
